38 * struct ethtool_cmd - DEPRECATED, link control and status
39 * This structure is DEPRECATED, please use struct ethtool_link_settings.
40 * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
41 * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
42 * physical connectors and other link features for which the
43 * interface supports autonegotiation or auto-detection.
44 * Read-only.
45 * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
46 * physical connectors and other link features that are
47 * advertised through autonegotiation or enabled for
48 * auto-detection.
49 * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
50 * @duplex: Duplex mode; one of %DUPLEX_*
51 * @port: Physical connector type; one of %PORT_*
52 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
53 * applicable. For clause 45 PHYs this is the PRTAD.
54 * @transceiver: Historically used to distinguish different possible
55 * PHY types, but not in a consistent way. Deprecated.
56 * @autoneg: Enable/disable autonegotiation and auto-detection;
57 * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
58 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
59 * protocols supported by the interface; 0 if unknown.
60 * Read-only.
61 * @maxtxpkt: Historically used to report TX IRQ coalescing; now
62 * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
63 * @maxrxpkt: Historically used to report RX IRQ coalescing; now
64 * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
65 * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
66 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
67 * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
68 * value will be %ETH_TP_MDI_INVALID. Read-only.
69 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
70 * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
71 * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
72 * When written successfully, the link should be renegotiated if
73 * necessary.
74 * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
75 * and other link features that the link partner advertised
76 * through autonegotiation; 0 if unknown or not applicable.
77 * Read-only.
78 * @reserved: Reserved for future use; see the note on reserved space.
79 *
80 * The link speed in Mbps is split between @speed and @speed_hi. Use
81 * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
82 * access it.
83 *
84 * If autonegotiation is disabled, the speed and @duplex represent the
85 * fixed link mode and are writable if the driver supports multiple
86 * link modes. If it is enabled then they are read-only; if the link
87 * is up they represent the negotiated link mode; if the link is down,
88 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
89 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
90 *
91 * Some hardware interfaces may have multiple PHYs and/or physical
92 * connectors fitted or do not allow the driver to detect which are
93 * fitted. For these interfaces @port and/or @phy_address may be
94 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
95 * Otherwise, attempts to write different values may be ignored or
96 * rejected.
97 *
98 * Users should assume that all fields not marked read-only are
99 * writable and subject to validation by the driver. They should use
100 * %ETHTOOL_GSET to get the current values before making specific
101 * changes and then applying them with %ETHTOOL_SSET.
102 *
103 * Deprecated fields should be ignored by both users and drivers.

2105 *
2106 * Some hardware interfaces may have multiple PHYs and/or physical
2107 * connectors fitted or do not allow the driver to detect which are
2108 * fitted. For these interfaces @port and/or @phy_address may be
2109 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2110 * Otherwise, attempts to write different values may be ignored or
2111 * rejected.
2112 *
2113 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2114 * are not available in %ethtool_link_settings. These fields will be
2115 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2116 * fail if any of them is set to non-zero value.
2117 *
2118 * Users should assume that all fields not marked read-only are
2119 * writable and subject to validation by the driver. They should use
2120 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2121 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2122 *
2123 * Drivers that implement %get_link_ksettings and/or
2124 * %set_link_ksettings should ignore the @cmd
2125 * and @link_mode_masks_nwords fields (any change to them overwritten
2126 * by kernel), and rely only on kernel's internal
2127 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2128 * %ethtool_link_mode_mask_t. Drivers that implement
2129 * %set_link_ksettings() should validate all fields other than @cmd
2130 * and @link_mode_masks_nwords that are not described as read-only or
2131 * deprecated, and must ignore all fields described as read-only.
